FIELD OF THE INVENTION

This invention relates generally to the field of the Internet of Things,and more specifically to wireless earbud charging and communicationsystems and methods.

BACKGROUND OF THE INVENTION

Currently, there are a number of headset or earbud configurationsavailable which allows a user to listen to audio streaming from hiscellular device. For example, the headset may comprise two earbudstethered together and optionally tethered to the cellular device or acompletely wireless configuration. However, each of these configurationshas deficiencies rendering its use less than ideal. For example, thecord that links the two earbuds together and/or links the earbuds to thecellular device often becomes tangled on clothing, hair, or otheraccessories potentially dislodging one or both earbuds from theirposition in the user's ear. The cord that links the two earbuds togetherand/or links the earbuds to the cellular device may restrict movement ofthe user as the user needs to avoid pulling the cord during use of thesystem (e.g., exercise, dancing, running, working, etc.).

Further, the communication methods used by available wireless earbudsare also less than ideal. Currently, a first earbud receives a packet ofinformation with a time stamp and then transmits that same packet ofinformation to a second earbud (i.e., a master-slave configuration, asshown in FIG. 17A). Once the time indicated in the time stamp occurs,the audio that was delivered to the first and second earbuds in thepacket is played. However, currently available wireless earbuds have twoinherent disadvantages with this approach. First, if the time indicatedon the time stamp passes and both earbuds do not have the packetcontaining the audio, then the earbuds do not play the audio, resultingin the first issue: poor signal reception. Second, to decrease poorsignal reception (i.e., drop-outs), the time between packet transmission(e.g., by computing device, mobile computing device, case, etc.) to anearbud, packet receipt by the earbud, and time stamp elapse at theearbud is increased (i.e., improve the chances of both earbuds receivingthe packet without the time indicated in the time stamp occurring orpassing), resulting in the second issue: latency between visual andaudio experiences (e.g., lip movement in video does not align withaudio). Further, current completely wireless earbuds have a master-slaveconfiguration in which the first earbud needs to receive the packetfirst and then retransmit the packet to the second earbud, the secondearbud receiving the retransmitted packet. This master-slaveconfiguration increases the time required to transmit data or audio toboth earbuds increasing the likelihood of poor signal reception (i.e.,dropouts). The shadow created by the user's head for the second earbudonly exacerbates these disadvantages since the wireless signal does notreadily penetrate the skull of the user. Occasionally, environments thatprovide adequate surfaces for wireless signal reflection and/or thatdecrease wireless signal dispersion (e.g., more wireless signal reachesintended destination) decrease dropouts and/or the need for latency, butonce the user moves outdoors or into a more open space, the latency andpoor signal reception problems return.

The poor signal reception and latency issues can be inverselyproportional: if latency is increased, audio-visual synchronization isdecreased (i.e., fewer dropouts, but audio lagging behind videoplayback), but if latency is decreased to synchronize audio and video,dropout frequency increases. Thus, a manufacturer is forced to choosewhich is more important to the user base as a whole: audio-visualsynchronization or signal (e.g., audio, data, information, etc.)reception quality (i.e., fewer dropouts).

Further, when using wireless earbuds, it is difficult for a user tocontinually track the location of their earbuds and provide the earbudswith the re-charge needed after only a few hours of use. However,current cases that allow storage of the earbuds in the case are bulkyand difficult to use. For example, if the earbuds are stored near thebottom of the case, the case includes a bulge or widening to accommodatethe earbuds which results in difficult one-handed PC APPLICATIONmanipulation of the mobile computing device positioned in the case. Forexample, housing the earbuds at the bottom of the case makes it harderfor a user's finger or thumb to reach all the rectangular surface areaof the cellular device's touch screen, especially along the top edge.Further, for example, current cases that allow storage of the earbuds ina top portion of the case, to avoid the issues described above, usuallyinclude a widening or bulge to accommodate the earbuds and/or include anoverall increased case thickness, resulting in the case being difficultto use and store in a user's pocket.

Mobile computing devices are repeatedly being redesigned to be lighter,thinner, and increasingly portable. To protect these lighter and thinnermobile computing devices, users' desire cases that protect their mobilecomputing device and house their earbuds but that do not result inincreased bulkiness to the overall slim design of the mobile computingdevice.

Thus, there is a need for new and useful wireless earbud charging andcommunication systems and methods. This invention provides such new anduseful systems and methods.

A subset of the plurality of sidewalls 14 or a bottom portion 18 mayfurther include a connector 19 (e.g., Lightning, IEEE 1394, Thunderbolt,DVI, HDMI, Serial, Universal Serial Bus, Parallel, Ethernet, Coaxial,VGA, PS/2, etc.) configured to electrically couple the case 10 to themobile computing device 12 or another computing device, for example asshown in FIG. 1A, FIG. 6A, and FIG. 8. In some embodiments, a subset ofthe plurality of sidewalls 14 define an earbud cavity 34 configured toreceive the wireless earbud 64, as described in further detail elsewhereherein.

The dividing layer 13 provides a surface for supporting and/orcontacting a back surface of a mobile computing device 12 positioned inthe first housing 22 in the case 10.

In some embodiments, the back panel 16 provides a surface for supportingand/or contacting one or more electronic components positioned in thesecond housing 38 in the case 10. For example, one or more electroniccomponents may include, but not be limited to, a battery 32, one or morePCBs, a switch mechanism 62, and an earbud charging contact 76. In someembodiments, as shown in FIG. 6C, the back panel 16 includes one or morecamera apertures 24 extending there through for revealing, for example,a camera or flash associated with a mobile computing device 12 disposedin the case 10. In some embodiments, the back panel 16 is planar orsubstantially flat. For example, the back panel 16 may not include anywidening or bulge to accommodate one or more wireless earbuds 64 in thecase 10 or any other component.

In some embodiments, as shown in FIGS. 7A-7B, the second housing 38houses one or more printed circuit boards (PCBs) for controlling thefunctionality of the case 10, mobile computing device 12, and/or earbuds64. As shown in FIG. 8, the PCBs may be tiered, layered, and/orstair-stepped in the second housing 38 to reduce thickness of the case10 and/or to give corners of the case 10 a rounded profile. For example,as shown in FIG. 8, a top PCB 26 and a center PCB 30 may be positionedin the second housing 38 of the case 10 parallel to the back panel 16and adjacent to the battery 32. A bottom PCB 28 may be positioned in thefirst housing 22 adjacent to the mobile computing device 12, asdescribed in further detail elsewhere herein.

The top PCB 26 functions to charge a rechargeable battery in one or moreearbuds 64 and/or to detect a presence of one or more earbuds 64positioned in the earbud cavity 34 in the top portion 20 of the case 10.The top PCB 26 comprises one or more charging contacts 76 for one ormore wireless earbuds 64 and/or an earbud detection switch 62, forexample to turn off a wireless signal emanating from the case 10 or themobile computing device 12 when the one or more earbuds 64 arepositioned in the earbud cavity 34 in the top portion 20 of the case 10.The charging mechanism and wireless signal switch are described infurther detail elsewhere herein.

The bottom PCB 28 includes a case charging receptacle or jack, acomputing device charge switch (i.e., activate or deactivate charging ofthe mobile computing device 12 using the battery disposed in the case),and/or one or more optical (e.g., LED, OLED, etc.) battery chargeindicators. In one embodiment, a user manually activates or deactivatescharging of the mobile computing device 12 disposed in the case 10 usingthe computing device charge switch. In one embodiment, one or more PCBsof the system automatically detect a charge status of the mobilecomputing device 12 disposed in the case 10 and activate or deactivatecharging of the mobile computing device 12 disposed in the case 10accordingly. The top 26 and bottom 28 PCBs are easily, readily, andaffordably replaceable or interchangeable to tailor the case 10 to amodel or type of mobile computing device 12.

In one embodiment, as shown in FIGS. 7A-7B, the center PCB 30 includesone or more wireless antennas 36, one or more processors 31, and/or abattery management system 29. Alternatively, the center PCB 30 mayinclude one or more wireless antennas 36 and one or more processors 31.Alternatively, the center PCB 30 includes a battery management system 29and one or more processors 31. The center PCB 30 is positioned in thecase 10 to limit or reduce the need to change the center PCB 30 in thecase 10 for different models and/or types of mobile computing devices12. The center PCB 30 is electrically coupled by flex wires or cables tothe top 26 and bottom 28 PCBs to control and provide power to or receivepower from or input control signals from the top 26 and bottom 28 PCBs.

The processor 31 of the center PCB 30 may be a general purposemicroprocessor, a digital signal processor (DSP), a field programmablegate array (FPGA), an application specific integrated circuit (ASIC), orother programmable logic device, or other discrete computer-executablecomponents designed to perform the functions described herein. Theprocessor 31 may also be formed of a combination of computing devices,for example, a DSP and a microprocessor, a plurality of microprocessors,one or more microprocessors in conjunction with a DSP core, or any othersuitable configuration.

In some embodiments, the processor 31 is coupled, via one or more buses,to the memory in order to read information from, and optionally writeinformation to, the memory. The memory may be any suitablecomputer-readable medium that stores computer-readable instructions forexecution by the processor 31. For example, the computer-readable mediummay include one or more of RAM, ROM, flash memory, EEPROM, a hard diskdrive, a solid state drive, or any other suitable device. In someembodiments, the computer-readable instructions include software storedin a non-transitory format. The software may be programmed into thememory or downloaded as an application onto the memory. The software mayinclude instructions for managing or running a communication systemand/or one or more programs or applications of the case 10, as describedelsewhere herein.

In some embodiments, the top 26 and center 30 PCBs are combined into onePCB; the bottom 28 and center 30 PCBs are combined into one PCB; or thetop 26, center 30, and bottom 28 PCBs are combined into one PCB. In someembodiments, less than or more than three PCBs may be used to achievethe desired functionality in the case 10.

In some embodiments, as shown in FIGS. 7A-7B, the antennas 36 arepositioned in the bottom corners of the bottom portion 18 of the case10. The corner position of each antenna 36 functions to provide an airgap between the antenna 36 and the sidewalls 14 of the case 10 to allowthe antennas 36 to receive and transmit data more effectively. In someembodiments, the antenna 36 of the center PCB 30 includes one or both ofa receiver and a transmitter. The receiver receives data over acommunication network and demodulates the received data. The transmitterprepares data according to one or more network standards and transmitsdata over a communication network. In some embodiments, a transceiverantenna acts as both a receiver and a transmitter for bi-directionalwireless communication. In some embodiments, the center PCB 30 includesa first transceiver (or first transmitter) and a first antenna dedicatedto a first earbud 64 a and a second transceiver (or second transmitter)and a second antenna dedicated to a second earbud 64 b. In someembodiments, a first antenna, receiver, or transceiver receives awireless data transfer from a mobile computing device 12 and a secondantenna, transmitter, or transceiver transmits a plurality of wirelessdata transfers directly to at least a first wireless earbud 64 b and asecond wireless earbud 64 b. In some embodiments, the first wirelessearbud 64 a receives the plurality of wireless data transfers at a firstfrequency and the second wireless earbud 64 b receives the plurality ofwireless data transfers at a second frequency. Alternatively, in someembodiments, the first wireless earbud 64 a receives the plurality ofwireless data transfers at a first frequency, the first frequencycomprising a first wave comprising a first amplitude: the secondwireless earbud 64 b receives the plurality of wireless data transfersat a second frequency, the second frequency comprising a second wavecomprising a second amplitude. In some such embodiments, the firstfrequency and the second frequency are the same.

The center PCB 30 may further include a battery management system 29.The battery management system 29 functions to, for example, protect thebattery 32 from operating outside its safe operating area (i.e., voltageand current condition over which device can be operated withoutself-damage), monitoring the state of the battery 32, controlling theenvironment of the battery 32, and/or battery balancing (i.e.,maximizing capacity of battery to increase battery longevity). In someembodiments, the battery management system 29 includes charging order orprioritization. In one embodiment, the battery management system 29prioritizes charging the mobile computing device 12 first and thebattery 32 disposed in the case 10 second. In one embodiment, thebattery management system 29 prioritizes charging the battery 32disposed in the case 10 first and the mobile computing device 12 second.In one embodiment, the battery management system 29 splits chargingcapacity equally, proportionally, or randomly between the battery 32disposed in the case 10 and the mobile computing device 12. In someembodiments, the battery 32 is managed so that it does not dischargecompletely to recharge the mobile computing device 12. For example, thebattery 32 may be allowed to discharge to a predetermined threshold(e.g., 50%, 60%, 70%, 80%, 90%, etc. of its rated capacity) to chargethe mobile computing device 12 disposed in the case 10 so that apercentage of the battery power remains for charging one or morewireless earbuds 64 disposed in the case 10.

As shown in FIGS. 7A-7B, FIG. 8, and FIG. 10, the second housing 38further includes a rechargeable battery 32 disposed therein andelectrically coupled to the center PCB 30, top PCB 26, and bottom PCB28. In some embodiments, the rechargeable battery 32 is a nickelcadmium, nickel-metal hydride, lead acid, lithium ion, or lithiumpolymer battery. In one non-limiting example, the rechargeable battery32 is a lithium ion battery. In one embodiment, as shown in FIG. 10, thebattery 32 is positioned parallel to the back panel 16 in the secondhousing 38 defined by the dividing layer 13 and the back panel 16. Amid-section of the back panel 16 of the case 10 has an outer surface 40that forms the outside surface of the case 10, the inner surface 42 ofthe mid-section of the back panel 16 is directly against the backsurface of the battery 32. The front surface 44 of the battery 32 isdirectly against the dividing layer 13.

In some embodiments, the dividing layer 13 at least partially comprisesa sealing layer to further reduce a thickness of the case 10. In somesuch embodiments, an adhesive side of the sealing layer is directlyagainst the front surface 44 of the battery 32, and the non-adhesiveside of the sealing layer is positioned directly against the back sideof the mobile computing device 12 positioned in the case 10. Saidalternatively, a back surface of the rechargeable battery 32 ispositioned against the back panel 16 and a front surface 44 of therechargeable battery 32 is adjacent to and secured by a sealing layer.In some embodiments, the sealing layer minimizes thickness of thedividing layer 13 and therefore the overall thickness of the case 10. Insome embodiments, the sealing layer may employ a pressure sensitiveadhesive to bond a membrane or other material to the battery 32 tosecure the battery 32 in the second housing 38. Non-limiting examples ofpressure sensitive adhesives include: natural rubber, vinyl ethers,acrylics, butyl rubber, styrene block copolymers, silicones, or nitrilesmixed with a resin, for example terpene-phenol, terpenes, aromaticresins, and hydrogenated hydrocarbon resins. In some embodiments, thesealing layer may employ a structural adhesive, for example epoxies,cyanoacrylates, urethanes, or acrylics, that secures a thin membrane ormaterial over the battery 32 to secure the battery 32 in the secondhousing 38. In some embodiments, the dividing layer 13 and/or sealinglayer is 0.05 to 0.5, 0.05 to 0.1, 0.1 to 0.15, 0.15 to 0.2, 0.2 to0.25, 0.25 to 0.3, 0.3 to 0.35, 0.35 to 0.4, 0.4 to 0.45, or 0.45 to 0.5millimeters thick. In one non-limiting embodiment, the sealing layer is0.2 to 0.3 millimeters thick.

The bottom portion 18 of the case 10, as shown in FIG. 6A and FIG. 7B,houses the bottom PCB 28 in some embodiments and provides a casecharging receptacle or jack, a computing device charge switch, and/orapertures to view one or more optical (e.g., LED, OLED, etc.) batterycharge indicators.

The top portion 20 of the case 10, as shown in FIGS. 1A-1B, FIGS. 6A-6C,and FIGS. 11A-11B, includes an earbud cavity 34 configured to receiveone or more wireless earbuds 64. In some embodiments, a subset of theplurality of sidewalls 14, the back panel 16, and a second portion ofthe front panel 15 together define the earbud cavity 34. Alternativelyor additionally, in some embodiments, the earbud cavity 34 is positionedadjacent to the first housing 22, the dividing layer 13, and the secondhousing 38 and/or parallel to the front panel 15 and the back panel 16.For example, as shown in FIG. 1D, the earbud cavity 34 and/or one ormore wireless earbuds 64 positioned in the earbud cavity 34 mayintersect a first housing longitudinal plane 65, a dividing layerlongitudinal plane 67, and a second housing longitudinal plane 69. Saidalternatively, the earbud cavity 34 and/or one or more wireless earbuds64 positioned in the earbud cavity 34 are inline with a first housingplane 65, a dividing layer plane 67, and a second housing plane 69. Saidalternatively, the earbud cavity 34 and/or one or more wireless earbuds64 positioned in the earbud cavity 34 share a horizontal plane orlongitudinal plane 65, 67, 69 with the first housing 22, dividing layer13, and second housing 38. In some embodiments, a battery 32, one ormore charging contacts 76, and/or one or more wireless earbuds 64 allshare or are positioned in a second housing longitudinal plane 69, forexample between the dividing layer 13 and the back panel 16. Further forexample, as shown in FIG. 1E, the earbud cavity 34 and/or one or morewireless earbuds 64 positioned in the earbud cavity 34 may intersect afront panel longitudinal plane 61, a dividing layer longitudinal plane67, and a back panel longitudinal plane 63. Said alternatively, theearbud cavity 34 and/or one or more wireless earbuds 64 positioned inthe earbud cavity 34 are inline with a front panel plane 61, a dividinglayer plane 67, and a back panel plane 63. Said alternatively, theearbud cavity 34 and/or one or more wireless earbuds 64 positioned inthe earbud cavity 34 share a horizontal plane or longitudinal plane 61,67, 63 with the first housing 22, dividing layer 13, and second housing38.

FIG. 9A shows a side view of a reference case 10R in which an earbud 64Ris positioned behind a first housing 22R and dividing layer 13R, behinda mobile computing device 12R disposed in the reference case 10R. Thisorientation results in an overall reference case thickness T1 plus T3.In contrast, as shown in FIG. 9B and FIGS. 1D-IE, the case 10 describedherein has one or more earbuds 64 positioned adjacent to, intersecting,or sharing a longitudinal or horizontal plane with the first housing 22,the dividing layer 13, and the second housing 38, as described elsewhereherein, resulting in an overall case thickness T1, which is less than T1plus T3. In some embodiments, as shown in FIG. 9C, a thickness T1 of thecase 10 does not exceed 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, 15 mm, 16 mm,17 mm, 18 mm, 19 mm, or 20 mm. In one embodiment, a thickness T1 of thecase 10 does not exceed 19.0 mm. Further, in some embodiments, as shownin FIG. 9C, a thickness T2 of the case 10 does not exceed 8 mm, 9 mm, 10mm, 11 mm, 12 mm, 13 mm, 14 mm, 15 mm, or 16 mm. In one embodiment, athickness T2 of the case 10 does not exceed 14.5 mm. In someembodiments, T1 is equal to T2; in some embodiments, T1 is differentthan T2. In some embodiments, as shown in FIG. 6C, a length L of thecase 10 does not exceed 110 mm, 120 mm, 130 mm, 140 mm, 150 mm, 160 mm,170 mm, or 180 mm. In one embodiment, a length L of the case 10 does notexceed 167 mm. In some embodiments, as shown in FIG. 6C, a width W ofthe case 10 does not exceed 50 mm, 60 mm, 70 mm, 80 mm, 90 mm, or 100mm. In one embodiments, a width W of the case 10 does not exceed 75 mm.

In some embodiments, the top portion 20 includes more than one earbudcavity 34, such that each earbud cavity 34 houses one earbud 64 or eachearbud cavity 34 houses more than one earbud 64. Alternatively, in someembodiments, one or more earbuds 64 are housed externally to the case10, as shown in FIGS. 5A-5C, and/or a top portion 20 of the case 10including the earbud cavity 34 is removeable and/or interchangeable witha second top portion 23 that does not include an earbud cavity, as shownin FIG. 6D. In some such embodiments, the second top portion 23functions to secure and/or protect the mobile computing device 12 whencoupled to the bottom portion 18 when, for example, the user does notdesire to have one or more earbuds 64 with him/her or the user isparticipating in an activity involving water. Alternatively, in someembodiments, as shown in FIG. 6E, the second top portion includes one ormore Universal Serial Bus (USB) ports 41 for matingly receiving a USBdrive 49 or USB connector/adapter 51, a credit card reader 43, a scanneror projector 45, or a breathalyzer 47. The second top portion 23 may, insome embodiments, include a flashlight, kickstand, keyboard (e.g.,qwerty), a photo enhancement, a wall plug (i.e., to directly charge case10 and/or mobile computing device 12 disposed in the case 10 from a walloutlet), a projector module (i.e., to project images from the mobilecomputing device 12 onto a surface), a solar power panel (e.g., forcharging the case 10 and/or a mobile computing device 12 disposed in thecase 10), a thermal imager (e.g., an infrared camera to detect heat), abottle opener, an electric lighter, an external speaker, a contactlesswireless charger (e.g., for induction charging), a scanner (e.g., forreading near-field communication tags, QR codes, barcodes, etc.), astrobe light, a Selfie Flash (i.e., forward facing soft light forpictures), or a power bank (e.g., using USB connector/adapter 51 topower additional devices using the battery 32 in the case 10).

In some embodiments, the second top portion, for example a credit cardreader 43, may receive charge from a battery 32 disposed in the case 10via earbud charging contacts 76, as shown in FIG. 6F. The second topportion may receive charge and/or transmit data back to the case 10 orreceive data from the case 10 directly via one or more earbud chargingcontacts 76 or via wireless communication (e.g., Bluetooth). In anotherembodiment, the second top portion may receive charge and/or transmitdata to or receive data from a mobile computing device 12 indirectly viathe case 10 (e.g., via connector 19) or directly using wirelesscommunication. In some embodiments, only one earbud charging contact 76is required to charge and/or transmit data to or from the second topportion; in other embodiments, more than one or a plurality of earbudcharging contacts 76 is required to charge and/or transmit data to orfrom the second top portion.

In some embodiments, as shown in FIGS. 6A-6C and FIGS. 11A-11B, aperimeter of an opening of the earbud cavity 34 is concave or has aconcave shape so that a top portion 46 and/or a front portion 35 and aback portion 37 of each earbud 64 is exposed in the earbud cavity 34allowing each earbud 64 to be removed from the earbud cavity 34 using apinching mechanism or method. For example, as shown in FIG. 11B, a usermay use an index finger and thumb to grip or pinch the front portion 35and the back portion 37 of the earbud 64 simultaneously or substantiallysimultaneously to insert or remove the earbud 64 from the earbud cavity34. Alternatively, in some embodiments, a perimeter of an opening of theearbud cavity 34 has a linear or convex shape so that an earbud 64within the earbud cavity 34 is unexposed but inline with the top portion20 of the case 10. Alternatively, in some embodiments, one or moreearbuds 64 may protrude from the earbud cavity 34 in the top portion 20of the case 10 for easy removal of the one or more earbuds 64 from thetop portion 20 of the case 10.

In some embodiments, the top portion 20 of the case 10 further includesa locking mechanism 48 to removably secure one or more earbuds 64 withinthe earbud cavity 34 of the top portion 20 of the case 10, as shown inFIGS. 12A-12B. The locking mechanism 48 is adjacent to the first housing22, along a top edge 21 of the mobile computing device 12, adjacent tothe earbud cavity 34. Since the earbud cavity 34 does not consume theentire volume of the top portion 20, the position of the lockingmechanism 48 (either to the left or right (adjacent to) of the earbudcavity in the top portion) prevents the locking mechanism 48 from addingadditional length and thickness to the top portion 20 of case 10. Asshown in FIG. 12A, the locking mechanism 48 encased in the top portion20 is horizontally H in-line with the earbud cavity 34, vertically Vin-line with the first housing 22 and the second housing 38 of the case10, as shown in FIG. 12A. This configuration does not increase theoverall case width W. In some embodiments, the locking mechanism 48includes a stationary lock for the first earbud 64 a and sliding lockfor the second earbud 64 b. For example, the locking mechanism 48 mayinclude a stationary stop 50 on a first side of the locking mechanism 48and a movable stop 52 on a second side of the locking mechanism 48.

During use, as shown in FIG. 12B, a slider 54 on the second side of thelocking mechanism 48 is horizontally adjusted, maneuvered, or displacedby applying horizontal force F to the slider 54 to compress a spring orseries of springs 56 in the locking mechanism 48 to horizontallydisplace the movable stop 52 on the second side of the locking mechanism48. The first earbud 64 a is positioned against the stationary stop 50on the first side of the locking mechanism 48, and the second earbud 64b is positioned next to the first earbud 64 a adjacent to the secondside of the locking mechanism 48 next to the movable stop 52. Release ofthe force F applied to the slider 54 allows the movable stop 52 tohorizontally contact and secure or lock into place the second earbud 64b. Alternatively, in some embodiments, the locking mechanism 48 includesa stationary lock for both earbuds 64, such that each earbud 64 issnapped into the earbud cavity 34 in the top portion 20 of the case 10.Alternatively, in some embodiments, the locking mechanism 48 includes asliding lock for both earbuds 64. For example, each side of the lockingmechanism 48 may include a slider 54 to compress a spring or series ofsprings 56 and horizontally displace a movable stop 52. In someembodiments, maneuvering the slider 54 compresses any linear orrotational force applying element (e.g., plastic spring arm, rotary coilspring type of release, etc.) that achieves the same endpoint of lockingthe earbud 64 in the earbud cavity 34 of the case 10.

Alternatively, in some embodiments, the locking mechanism 48 includes apressure locking-releasing mechanism. For example, a user may applyforce or pressure to an earbud 64 to removably secure or lock the earbud64 in the earbud cavity 34 and to release or unlock the earbud 64 fromthe earbud cavity 34. The force or pressure used to secure or lock theearbud 64 in the earbud cavity 34 may compress or load a spring andactivate a lock, whereas the force or pressure used to release or unlockthe earbud 64 from the earbud cavity 34 may decompress or expand thespring to a normal (i.e., unloaded) position.

Further, as shown in FIGS. 13A and 13D, the earbud cavity 34 in the topportion 20 of the case 10 includes at least one earbud charging contact76 per earbud 64. The earbud charging contact 76 is configured tocontact and charge the wireless earbud 64 when the wireless earbud 64 ispositioned in the case 10. The earbud charging contact 76 aligns withand interfaces with a conductive surface 78 on the body 70 of the earbud64 (also shown in FIGS. 2A-2F and FIGS. 3A-3D). The earbud chargingcontact 76 is disposed within the second housing 38 defined by thedividing layer 13 and the back panel 16 to minimize a thickness T of thecase 10. For example, the earbud charging contact 76 may be positionedbetween the dividing layer 13 and the back panel 16, as shown in FIGS.1D-1E, 9B. In some embodiments, the earbud charging contact 76 isfurther positioned adjacent to or in the same plane as a rechargeablebattery 32 disposed in the second housing 38.

In some embodiments, the fin 68 of the earbud 64 is shaped such that theearbud 64 only fits into the earbud cavity 34 in one orientation so thatthe conductive surface 78 on the body 70 of the earbud 64 alwaysinterfaces with the earbud charging contacts 76 in the second housing38. In some embodiments, the earbud charging contacts 76 are springloaded pins or stationary pins. In some embodiments, the first earbud 64a receives charge from the case 10, for example using the earbudcharging contacts 76, and the second earbud 64 b receives charge fromthe first earbud 64 a using, for example, induction or one or moreconductive surfaces on the second earbud 64 b interfacing with acharging contact on the first earbud 64 a. In one embodiment, the firstand second earbuds 64 a/64 b both receive power from the case 10 viainduction charging and/or conductive charging.

Further, as shown in FIG. 13A, the earbud cavity 34 in the top portion20 of the case 10 includes a switch mechanism 62 that detects thepresence or absence of the earbuds 64 in the earbud cavity 34. In someembodiments, the switch mechanism 62 is disposed in the second housing38 defined by the dividing layer 13 and the back panel 16. Thisconfiguration prevents unnecessary width W or thickness T in the case 10and prevents any bulging, swelling, or protrusions in the case 10 toaccommodate the fins 68 of the earbuds 64 and/or the switch mechanism62.

In one non-limiting example, when the switch mechanism 62 is activated(i.e., earbuds are in the earbud cavity), the battery 32 recharges therechargeable battery of the earbuds 64 positioned in the earbud cavity34; when the switch mechanism 62 is deactivated (i.e., earbuds are notin the earbud cavity), the battery 32 does not supply power to rechargethe earbuds 64 in the earbud cavity 34. Further in some embodiments,when the switch mechanism 62 is activated (i.e., earbuds are in theearbud cavity), the wireless signal emanating from the case 10 and/ormobile computing device 12 is turned off or deactivated; when the switchmechanism 62 is deactivated (i.e., earbuds not in the earbud cavity),the wireless signal emanating from the case 10 and/or mobile computingdevice 12 remains active or on.

In one embodiment of the switch mechanism 62, the mobile computingdevice 12 is communicatively coupled to the case 10. In one embodimentof the switch mechanism 62, the mobile computing device 12 iscommunicatively coupled to one or more earbuds 64. For example, when anearbud 64 is being recharged in the case 10, the earbud 64 may sensethat it is being recharged and send a signal to the case 10 and/ormobile computing device 12 to deactivate a wireless signal emanatingfrom the case 10 and/or mobile computing device 12. The switch mechanism62 conserves battery life since wireless signal broadcasting only occurswhen the earbuds 64 are not positioned in the earbud cavity 34 in thetop portion 20 of the case 10.

The switch mechanism 62 may comprise a toggle switch. For example,positioning an earbud 64 in the earbud cavity 34 deflects D the lever toan “off” state, as shown in FIG. 13A, and removal of the earbuds 64allows a spring in the switch mechanism 62 to return the lever to a“normal” or “on” state. The switch mechanism 62 may comprise a selectorswitch similar in functionality to the toggle switch, except allowingtwo or more states (e.g., wireless off and charging on, wireless on andcharging on, wireless off and charging off). The switch mechanism 62 maycomprise a lever actuator switch similar in functionality to the toggleswitch and selector switch, except further including a roller bearing orsimilar device to prevent the lever from wear over time from repeateduse. The switch mechanism 62 of the top PCB 26 is electrically coupledto the center PCB 30 so that charging and wireless signal broadcastingare controlled by the center PCB 30.

In some embodiments, a sidewall 14, top portion 20, bottom portion 18, afront panel 15, or back panel 16 of the case 10 further comprises alocater switch for locating one or more wireless earbuds 64. The switchwhen depressed or activated may cause one or more wireless earbuds 64 tobroadcast an audible signal (e.g., beep, buzz, spoken word(s), ringtone, etc.) to determine a location of the one or more wireless earbuds64. For hard of hearing or deaf users, the locater switch may activatean optical signal (e.g., LED) in the wireless earbud 64 for a visualdetermination of the wireless earbud's location.

Block S320 functions todecrease a perceived lag or latency between a visual event on a displayof a computing device (e.g., lips forming words, explosion, car beingturned on, etc.) and an audio event heard by a user in relation to thevisual event (e.g., words being spoken, a sound of the explosion, soundof a car engine starting, etc.). As described elsewhere herein, if apacket (e.g., data, audio, etc.) is transmitted to an earbud or if anearbud receives a packet of information (e.g., data, audio, etc.) and along time elapses before the time stamp occurs or passes (i.e.,latency), the user may perceive a disconnect or lag between a visualevent on the display and an audio event heard in relation to the visualevent. Allowing a user to tune or adjust the latency period to minimizeor elongate this latency period enables the user to achieve her desiredaudio-visual experience. In some embodiments, adjusting the switchoccurs automatically, for example, upon the earbud, computing device,case, or other device sensing that the user is viewing a video, movie,or other combination of audio and visual, and automatically moving,adjusting, or manipulating the switch to achieve higher audio-visualsynchronization. In some embodiments, adjusting the switch occursmanually, for example by a user, manufacturer, designer, etc. of themethod.

In some embodiments, if the user is viewing a movie, video, or otheraudio-visual event indoors or in a semi or fully enclosed space, theuser may not experience any dropouts due to the shortened latencybetween packet receipt and use (e.g., audio/video play). However, insome embodiments, if the user is viewing a movie, video, or otheraudio-visual event outdoors or in a semi or fully open environment, theuser may experience one or more dropouts due to the shortened latencybetween packet transmission to the earbud or packet receipt by theearbud and packet use by the earbud.

As shown in FIG. 22, one embodiment of a method 300 for manipulation ofdata transfer modes includes block S330: if a user desires high signalreception quality, adjusting the switch to increase the latency betweenpacket transmission to an earbud and time stamp of packet use by theearbud. Block S330 functions to decrease poor signal reception ordropouts during audio streaming (e.g., music, podcast, etc.). Asdescribed elsewhere herein, if a packet (e.g., data, audio, etc.) istransmitted (e.g., by a mobile computing device, computing device, case,etc.) to an earbud and not enough time elapses before the time stampoccurs (i.e., time stamp passes without the earbud receiving the packetof information), the user may experience poor signal reception (i.e.,one or more dropouts) in the audio. Allowing a user to tune or adjustthe latency period to minimize the number of dropouts the userexperiences enables the user to achieve his or her desired audioexperience. In some embodiments, adjusting the switch occursautomatically, for example, upon the earbud, computing device, case, orother device sensing that the user is streaming audio, the switch isautomatically moved, adjusted, or manipulated to achieve higher audiosignal reception quality. In some embodiments, adjusting the switchoccurs manually, for example by a user, manufacturer, designer, etc. ofthe method.
